 A factory class, used for creation of operation objects and queueing them for execution.

 Operation objects. Every operation class derives from CLogServOperationBase.

 View objects.Every view class derives from CLogServViewBase.

 @see CLogServViewBase

 @see CLogServViewEvent

 @see CLogServViewRecent

 @see CLogServViewDuplicate

 The class also offers a factory method for views creation - NewViewL().

 All created objects accept a reference to the MLogServOperationManager object and add themselves to the

 operations queue.
